Swordfish

Has anyone successfully used the USB module with either of those PIC's?

madru, Here is a program written for the 18F2455 it is the little brother of the 18F2550 (I do not have a 18F2550). Anyway here is the program and it works. { ***************************************************************************** * Name : Test_RE3.BAS * * Author : [select VIEW...EDITOR OPTION...

madru,

Try adding this in the P18F2550.inc There is no PORTD in this PIC so it is not needed.
If this is no help, could you post some code?

madru,

Try adding (Config MCLRE = OFF) to your source code.

Not sure if you need to modify the 18F2550.bas file.

Ryan and Francis,

After looking at Doj "18K K series" post I noticed that I missed that
"#variable _maxram = $0F60 // 3936 bytes of user RAM" needs to be changed.
You should make that change in the 18F26K20.bas file.

Ryan, I am glad it is working for you as well.

Francis, I just thought it was odd that it worked for 18F25k20 and not 18F26k20. So I looked at each PIC's ".bas" in the include directory to see if there are any differences. #variable _maxaccess and #const _ram_banks were different. Then I looked at the data sheet in section 5.0 MEMORY ORGANIZATIO...

Francis, Open this file located in the Swordfish\Includes "18F26K20.bas" with your favorite text editor. Then change this line from: #variable _maxaccess = $80 // access ram is 128 bytes To: #variable _maxaccess = $60 // access ram is 96 bytes Save the file, close Swordfish if it was open. Reopen Sw...

RD, I could not get your code to compile as well. Even a simple blink code will not compile without errors. But I think I know the problem. You need a newer version of the MPASMWin.exe that is located in the Bin folder. On my computer I have MPLAB v8.0 (it is not the latest but) copy MPASMWin. exe f...

Liak,

I found it on the Wiki site here is the link http://www.sfcompiler.co.uk/wiki/pmwiki ... er.Plugins

Have fun,

Hi Charlie, Here is some code that woked for me a while back. This one use the UART and it is for 18F4520. // This program measure the temp from a DS18S20 temp sensor on a // EasyPic4 demo borad and sends it to the PC via the USART Device = 18F4520 Clock = 8 // import modules... Include "DS18S20.bas...

Marc, You need to open the 18F4553.bas from the include folder and edit this line then save it. From: #const _adc = $05 // 5 ADC channels available To: #const _adc = $0D // 13 ADC channels available I have seen this a few times with the A/D modules when the include files do not match the data sheet ...

Ryan,

There are two ways of editing locked files.

One is to open it in a text editor like notepad or wordpad and then save it.

The other inside of Swordfish, is to open the file and double click on the lock and edit the file then save.

speed 64,

Glad to hear you got the ADC module working.

Are you sure have 5V on AN2? Can you measure that?

Also show you code

speed64, Check out this post http://www.sfcompiler.co.uk/forum/viewtopic.php?t=438&highlight= Like you I had a problem with the ADC but on the PIC18F2455. Changing the lines in 18F2553.bas from: #const _adc = $05 // 5 ADC channels available to: #const _adc = $0A // 10 ADC channels available may solv...

Doug,

Glad to help.

Yes the enable got me as well.
